problem with ported upper installation. HELP!!!

**SpectorV** · 08-06-2004, 06:18 PM

get a friends car and double check all connections if you can find the same year car. I am scared of taking my stuff off... im gonna mark each line and what not so i know where they go.

well i talked to a buddy and its pretty obvious is a vacuum leak somewhere so im going to get some carb cleaner and spray it around the different lines and see if i cant find where the leak is that way. this will most likely take all day tommorow but oh well.

hmm, ya, that sounds like a vaccum leak, I sometimes get something caught underneth the intake when i set it down, so it could be that or maybe you do have a vaccum line not hooked up. I really wish i could be there man.

i had the exact same prob when i was reinstalling my spacer a while back..turns out the gasket i used inbetween the upper and spacer was crap.

Mike - when you half-shafted the TB, did you do anything to the lip inside the TB or just half shaft it? If you overbored the TB, then you will have idle problems.

Did you use any gasket sealer when putting the upper back on? you might have a leak or the gasket might have slipped a little. the single ports sucked ass at slipping.

Did you do anything to the lower? if so, there are a whole lot of other things you could have done there.

As for the EGR, there should be a red and a green plastic/nylon tubing connecting to it. Double and then triple check that there isnt a crack in there. if there is, that is your problem. They snap really easily and will cause you all sorts of problems and since they are so small, you don't catch them being broken.

As much as you prolly dont want to hear this, I would take all the sensors off again and the intake off again. Put some RTV gasket maker on and reconnect everything. Make sure the vacuum hose under the upper mani is secure as well as everything else. Sometimes just redo-ing it helps more than you can think

alright well i just took it apart and put it back together again, and im still getting a loud whistling noise from the same place. Im thinking its that tube on the bottom side of the intake, should i put some sort of bracket around the rubber stuff to make sure its sealed on both ends? Thats really the only thing i can think of being that i checked any vacuum line i know of and its connected. This is gettin to be a real headache, i guess ill try putting brackets on there

Zim · 08-07-2004, 01:13 PM

rob you wanna get on aim if you can?

97Stallion · 08-07-2004, 02:30 PM

Mike, sorry I'm at work, we can play e-mail tag if you want. Robert.Doerr@shaw.af.mil

Zim · 08-07-2004, 02:32 PM

well, i just put my original intake back on thinking something may have been wrong with the new one... and sure enough, i get a nice POS whistle

Zim · 08-07-2004, 02:32 PM

ill tell you what.. . im now a pro at switchin these things out. It takes me about 10 minutes to get the thing off.

97Stallion · 08-07-2004, 02:35 PM

So even with the old intake one, you still get that whistle? E-mail me, I left my address above

thirstymate · 08-07-2004, 05:31 PM

have your replaced the gaskets at all.. could be your problem. the heat that those things go through kills them.

Zim · 08-08-2004, 10:10 AM

gaskets have all been replaced

thirstymate · 08-08-2004, 01:53 PM

after listening to those videos i really think its the tb.. my friend has a 5.0 gt and he put a bigger tb in and the whistle your getting is exactly i denticle to the whistle hes gettin .. his doesnt stall out though but i nmoticed that it only whistles when you gas it.. and that would be the tb, i know on my car there is a vaccum line that runs through it .. it might be the egr. not sure. but when you ground out your tb, you could have either messed with that or you could have widened it to much and now the tb isnt closing tight.. since you have switched between the intakes that definately not it .. try an auto parts store. find one that will sell you a new tb and if thats not it return it.

thirstymate · 08-08-2004, 01:53 PM

hah "i denticle" nice....

Ya, I said this previously also and in conclusion, this has got to be the problem. I just wonder why it stalls out. I still wouldn't take it to a dealer or anything, they'll charge you for just looking at it.

i dunno if theres any by you zim but just take it to a local shop that will do a free checkup

KrazyPony · 08-10-2004, 09:11 AM

Any update here Zim? You get it fixed?

Danger Dude · 09:25 AM

Well Zim called me at my office yesterday and we discussed his problem for over an hour. This is what I came up with. His car idles ok does it shake So it is not the PVC, IAC, EGR or a vacuum leak. The main issuse is the car will loose power and shut down and after a few moments it will get going again. He could have a intermittent TPS but that is a long shot

I have concluded his Fuel pump or a clog in the tank is the problem. He was telling me the Pump hums all the time. I think the pump output is weak or there is something stopping up the fuel. The car is suffering from fuel starvation and shut off. After a few moments the pump slowly builds pressure up and the car will start again and he can drive off for a while till it happens again. At Idle the car runs fine because the car is under zero load and there is enough fuel getting thru .

i took it to the stealership and they just called me telling me that they think its my chip screwing something up on my EEC. I think theyre full of shit and they want 200 dollars to take the chip off and run more tests. Corey they did mention the TB position sensor cause they said they think it may not be getting any voltage. I mentioned to him just hooking a voltometer up to the wires to check for voltage that way but he said that wouldnt work. (i think hes full of it) I dont want to pay the 200 dollars for him to remove my chip and run 20 minutes worth of tests on my computer. WTF should I do here?
